X-Bomber is a marionette tokusatsu TV series. Created by manga master Go Nagai, the show, produced by Cosmo Productions and Jin Productions, aired on Fuji TV from October 4, 1980 to March 28, 1981, with a total of 26 episodes (counting the pre-series pilot episode).

The show's opening and ending theme songs ("Soldier in the Space" and "The Drifting Galaxy", respectively) were done by the Japanese pop-rock group, Bow Wow, while Kazutaka Tazaki (of Baja Revolution) and Nakayuki Sakuraba (of Adbaloon) provided additional music for the show.

The year is 2999 and the Earth is at peace following the Space Wars. The tranquility of the human race is ensured by Earth Defense Force (EDF). Shortly before the turn of the fourth millennium the peace is broken by the appearance of a gigantic alien battle cruiser. Powerless to defend itself, the EDF's Pluto base is completely destroyed and the evil Commander Makara reveals the same fate awaits the Earth unless the mysterious F-Zero-One is handed over to her.

Oblivious to the existence of F-Zero-One, and fearful of Makara's terrible retribution, the EDF presses into action a new and untested weapon, the X-Project from its hidden moon-base.

The series then follows the adventures of the crew of the X-Bomber as they discover the nature of the F-Zero-One and try to protect it from the increasingly desperate and unstable Makara and her demanding overlord, the "Imperial Master".
